HOF-

IMPRGVEMENT IN HARVESTER-RAKES.

The Schedule `referred to in these Letters Patent and making part of the same.

I We,'AARoN PALMER and'OHAnLEs-W. PALMER, of

Brockport, county of Monroe, and State of N ew York, have invented certain Improvements in Harvesters, of which the following is a specification.

Nata/re and Object.

. 340, for raking apparatus, and consists in the conlbination of an adjustable reel with said apparatus in such a manner that it'may be raised and lowered during the progress of the machine, at the pleasure of the operator.

Description of Drawings.

Figure l, sheet 1, is an elevation of the apparatus as seen from the Arear ofthe machine.

Figure 2, sheet 2,v is a'vertical section through the axis of the driving-shaft.

Figure 3, sheet 3, is atop view asseen from the side of the machine where the power is applied.

Figure 4, sheet 4, is an end view, as seenv from the side of the machine where the power is applied.

' Figure 5, same sheet, is an end view from the grainside of the machine, and shows a chain for. driiingihe reel, instead of gearing,as in the otherviews.

Like letters refer to like parts in all the drawings.

A is the p ost for= supporting the entire raking and reeling devices, and it is iocate dupon the platform B or any other convenient portion of the machine, by which the rake-head may bebrought to coincide with a plane, parallel, or nearly so, to the center of the iinger-bar of the machine, the object of which will be hereafter explained.

At or near the upper vend of thepost 'A is a hollow arm or bracket, C, ot' metal, firmly secured to post A in any convenient manner.

Through said arm C extends a shaft or axle Z, which serves as a support for the arm that carries the reel, and upon its opposite end, or that nearest to the opera-tor, is fastened the lever '11, by which the reel is raised or lowered.

Upon the arm C vis a sle'eve,.Y, and upon its inner end, or that next to the post A, is a toothed or chainwheelto receive motion from any convenient drivingmechanism ofthe machine.

Upon the other end of said sleeve is another wheel for imparting motion to the reel, either by intermediate toothed wheels ora chain, as shown in fig. 5, the

action of which will be hereafter' explained.

Upon sleeve Y, which is upon the arm C, is a sleeve D, rtowhich the rake-arm is attached by means of a sleeve, d, formed on the side of sleeve D, one side of which, d, is left open for the'segment of abevel-wheel,

WV, which is fastened upon the rake-arm d, to partially turn in. The sleeve d serves as a collar upon the rakearm to hold it in workingcombination with the sleeve D,

Exterior to the sleeve D, but concentric with it, is an open sleeve, H, each end of which is fitted to work closeiy upon the sleeve Y or arm O, which carries it. .lie cylindrical portion of said open sleeve is made sufficiently large to permit the sleeve D to work freely within it, and a sufficient portion -of it is left open to permit the rake-arm to play back and forth within it.

At one end of said sleeve H, and within it, is a beveled toothed wheel, K; which engages with the segmentW to control the motion of the rake, as'explaine'd in the previous patent already referred to.

At L L, upon the sleeve H, are two arms, to which is pivoted the lifting-arm M, lsaid arm being T-shaped and attached to a sliding sleeve, N, that surrounds the 'which engage in holes in the face of the inner wheel upon the sleeve Y like the teeth of a clutch, and b v which motion is imparted to sleeves H and D, and

thence to the rake G.

Upon the outer extremity of the axis Z is fastened an arm, X, which extends forward over the front of the cutting apparatus sudiciently far to support the reel-shaft, so far forward of the cut grain upon the lplatform as that the reel beaters cannot strikev the gavel under any circumstances.

At or near the outer extremity of the arm X suitable bearings for the reel-shaft are mounted, and upon them the wheel R is supported. These bearings may also be made adjustable in arm X, as indicated in the drawings.

At 1, 2, and 3 are toothed wheels to impart motion from the sleeve Y to the reel R, and the diameter of these wheels may be so valied that any desired speed of the reel may be readily obtained, ory a chain and wheels may he substituted for the' gear wheels, shown at fig. 5, sheet 4.

Upon the opposite end of the axis Z from the reel,

'a lever, a, is fastened in such a position that the operator of the machine may easily reach it, and byv which the axis Z is pal'tiallyrotated to raise or lower the reel.

On any convenient point of the lever a a stop may be aiiixed to engage in notches or holes in an arc, as at m, upon the post A, for the purpose of holding the reel at any desired height. V

Upon a bracket, p, fastened upon the axis Z, is mounted a sliding rod fi, one end of which is forked, t0

When the rod c' is shovedfrom the operator, the

sleeves H and D will be moved from the inner end of 4the sleeve H, and the clutch-pins 'will then be released so 4that the rake may stop, and by using a spring, as at r, upon the shipping-rod r, they will be brought in contact.as soon as the pressure is removed from the shipper.

The operation is as follows:

Power. being applied to the sleeve Y, either by gear or belts applied at its inner end, and the pins s s of the sleeve H being engaged in the holes at s s on the sleeve Y, the rake' is caused to perform the same motions as specified in the patent already" referred to, the wheel K imparting motion to the segment W, causing the rake to sweep across the platform to remove the grain, which being accomplished, the rake is then lifted bythe arm M and carried up and over theI arm C, the gear-K and W guiding the rake to coincide with one of the beaters of the reel, and following it until it reaches a point at or near the front edge of the piatform. Pressure being applied'to the shipping-rod fi,

the sleeves H and D are disconnected, and the rake ceases its motion at the pleasure of the operator.

Claims.

l. The combination of the axis Z, the. hollow arm C', the arm X, and the lever n, for the purposes hereinbefore set forth.

2. The sleeve Y upon the ann C, for driving the reel, as hereinbefore set forth.

` 3. The sleeve Y upon arm O, in combination with the sleeves H and D, toothed gear K and W for imparting mot-ion to the rake, as 'hereinbefore set forth.

4. 'lhe Ysleeve Y, in combination with the sleeve H, arms L L, lifting-arm` M, projection t, and wheel O, upon bracket b, for the purposes set forth.

5. lhe slotted arm X, for sliding the reel bearings to and from the rake center, when such arm is mounted upon the axis Z, for the purposes set forth..
